Rheem Warranty Registration: How and When to Register
Registering your Rheem system within 60 days of installation unlocks the extended parts warranty, typically doubling parts coverage to 10 years. Miss that window and your coverage drops to the shorter base term. Here's exactly how to do it and what you need.
Deadline: 60 days from installation. Without registration within 60 days, coverage stays at the shorter base parts term. This is the most important step after your Rheem system is installed.
How to register your Rheem warranty
- Gather your information: the model and serial numbers for each component (on the data plate attached to each unit, and on your installation invoice), the installation date, and your installing dealer's details.
- Go to the official Rheem registration page (linked below) and enter your details. Register each component if prompted.
- Save the confirmation. Keep the registration confirmation with your proof of purchase, you'll need both if you ever file a claim.

Why it matters
Rheem registration covers both HVAC systems and Rheem water heaters. For tankless and tank water heaters, registration similarly extends the coverage term, the same 60-day discipline applies.
What you need to register
- Model number(s), on the unit data plate and installation invoice
- Serial number(s), same locations
- Installation date
- Installing dealer name/information
Keep the deadline and the paperwork in one place. Add your Rheem system to the free WarrantyRanger tracker the day it's installed, store the registration confirmation and we'll track your coverage dates.
